GPS in lieu of dme

[BrewMaster]

Could someone please direct me to the appropriate section in the AIM that talks about this. I thought it was around 1-1-19 or 1-2-3, but I finally have to swallow my pride and admit I can't find it.....

It's in 1-1-19. More specifically, its contained within paragraph (e).

More specifically, what are you looking for? When GPS can be used in lieu of DME, or what GPS systems are qualify to be used in lieu of.

AIM 1-2-3. Use of Suitable Area Navigation (RNAV) Systems on Conventional Procedures and Routes

c. Allowable Operations. Operators may use a suitable RNAV system in the following ways.
1. Determine aircraft position over or distance from a VOR (see NOTE 4 below), TACAN, NDB, compass locator, DME fix; or a named fix defined by a VOR radial, TACAN course, NDB bearing, or compass locator bearing intersecting a VOR or localizer course.
2. Navigate to or from a VOR, TACAN, NDB, or compass locator.
3. Hold over a VOR, TACAN, NDB, compass locator, or DME fix.
4. Fly an arc based upon DME.
These operations are allowable even when a facility is explicitly identified as required on a procedure (e.g., “Note ADF required”).
These operations do not include lateral navigation on localizer-based courses (including localizer back-course guidance) without reference to raw localizer data.
NOTE-
1. These allowances apply only to operations conducted within the NAS.
2.The allowances defined in paragraph c apply even when a facility is explicitly identified as required on a procedure (e.g., “Note ADF required”). These allowances do not apply to procedures that are identified as not authorized (NA) without exception by a NOTAM, as other conditions may still exist and result in a procedure not being available. For example, these allowances do not apply to a procedure associated with an expired or unsatisfactory flight inspection, or is based upon a recently decommissioned navaid.
3. Pilots may not substitute for the navigation aid providing lateral guidance for the final approach segment. This restriction does not refer to instrument approach procedures with “or GPS” in the title when using GPS or WAAS. These allowances do not apply to procedures that are identified as not authorized (NA) without exception by a NOTAM, as other conditions may still exist and result in a procedure not being available. For example, these allowances do not apply to a procedure associated with an expired or unsatisfactory flight inspection, or is based upon a recently decommissioned navaid.
4.For the purpose of paragraph c, “VOR” includes VOR, VOR/DME, and VORTAC facilities and “compass locator” includes locator outer marker and locator middle marker.

Ok, that makes me feel better, I was reading all this and that was about as close as I could get. I could have swore there was a very specific section on this, but I guess this is what I was looking for.

Many thanks!
